Lake Serre Poncon is an artificial lake in the southern French Alps. The lake is located on the border of both the Hautes Alpes and Alpes de Haute Provence departments in Provence Alpes Côte d'Azur. It is located in a strong tourist destination with many activities on offer. It is known as Sea in the Mountain.

This lake was created thanks to the establishment of a dam aimed at taming the Durance River, a tributary of the Rhône River. Before the dam, floods were commonplace and people had to be relocated with some villages being immersed. The construction of the 120 metre high dam ended in 1961. Lake Serre Poncon today supplies 16 hydroelectric power stations, which represents 10% of French hydroelectric production. The lake water is also used for irrigation, as well as drinking and industrial use. The preservation of the Serre Poncon Lake is operated by a local association ensuring the water quality as well as the management of the related ecotourism.
